Abstract

A washing appliance such as a dishwasher where a top-loading wash chamber is slidable out of cabinet for loading and unloading has a cabinet-mounted chamber lid which is power driven down onto the open top of the wash chamber during the washing cycle. Linear actuators or motors mounted in opposite sides of the appliance cabinet are coupled to opposite sides of the lid to pull the lid down when the chamber has been slid back into the cabinet. In a preferred embodiment rotating dc motors are used to rotate a threaded nut which in turn produces linear motion in a threaded shaft engaged within the nut and connected to the lid.

Mode-switching power supplies also require relatively expensive components such as inductors and capacitors with high operating voltages. In such white goods, it is common to control motor torque and speed using pulse width modulation (PWM) techniques to control the current supplied to the motor windings. Such PWM circuits also require relatively expensive components.

角ｔonの値が増減されると、出力電圧Ｖdcが増減される。The bridge rectifier BR charges the storage capacitor C3 of large value to provide a variable voltage DC power supply. The value of the output voltage is determined by phase switching the transistor Q 1 which is a gate isolated bipolar transistor (IGBT). The conduction angle of Q 1 is controlled by the microprocessor μP 1 to determine the motor torque of the appliance at various stages of the wash cycle. The conduction angle of Q 1 is shown by the waveform diagram of FIG. 2 showing the collector current I. When the value of the conduction angle t on is increased or decreased, the output voltage V dc is increased or decreased.

For triac phase control it is usually necessary to use an inductance of 2-5 mH. However, according to the power supply circuit of the present invention, the use of such an inductance can be avoided by utilizing the Miller effect. IGBT associated with Miller capacitance
The gate resistance of Q 1 causes the voltage to drop substantially linearly with time. The gate charge on Q 1 is discharged at a rate determined by the gate voltage and the gate resistance R9.

果たす。The bias power supply for Q 1 must meet two difficult requirements.
First, it must ensure proper operation on both 110 and 230 volt mains feeds. Second, it must ensure a fast start-up at power-up so that Q 1 does not possibly operate in a catastrophic linear mode. If Q 1 is off or in linear mode during the negative half cycle,
Due to the voltage difference between the collector and the gate, a current is generated for the bias power supply through the diode D2. Resistor R8 acts to isolate capacitor C4 which would otherwise prevent any momentary gate drive. Resistor R2 serves to protect diodes D1 and D2 during transient AC spikes that can cause reverse breakdown in either diode.

である。The power supply of the present invention offers a number of advantages in applications where the power dissipated in the brownout resistor R1 can be used successfully. Such advantages include no need for an inductor, avoiding the need for a PWM circuit for motor control, low voltage rating on the storage capacitor, low radio frequency interference, and electrical appliance standby. It is mentioned that the power consumption is low during operation.
Furthermore, only the value of one component needs to be changed between the power supply for 110 volt AC and the power supply for 230 volt AC. This value is the value of the lowering resistor which is realized by the moisture heating element of the appliance as already explained.
